Quiz: can you identify the world cities from their running heatmaps?

I could be wrong, but I’m pretty sure I recognize number 1. (Incidentally, as a planning device, I think heat maps like this are used far too little … They show the desire lines for an entire city, and are a great source of data on how people want to use their city)

From The Guardian:

Heat 1


They’re not all that easy:

Glasgow, Gdansk or Gothenburg:

Heat 2


Ljubljana, Lanzhou or Liverpool:

Heat 3
